| Breakthrough in using CRISPR-Cas9 to target fat cells Posted: 15 Dec 2021 05:41 PM PST Researchers describe a breakthrough using CRISPR-Cas9, a tool that has transformed molecular biological research, but whose use in the study of adipose tissue had been elusive. |
| Skin sensing made easier: Improved methods facilitate monitoring of body movement and health Posted: 15 Dec 2021 11:22 AM PST Scientists simplify fabrication methods and model human skin structure in designing wearable sensors. This methodology reduces costs, enhances scalability and modular fabrication, and provides effective, wide-ranging sensitivity in wearable pressure sensors. |
| Innovative textile vents to release heat when you sweat Posted: 15 Dec 2021 11:21 AM PST Materials scientists have developed a lightweight material that traps thermal energy when dry, but when the person starts sweating, opens a series of tiny vents to let heat escape and re-closes them to retain heat once they are dry again. Using physics rather than electronics to open the vents, the material has potential as a patch on various types of clothing to help keep the wearer comfortable in a wide range of situations. |
| Reducing copper in the body alters cancer metabolism to reduce risk of aggressive breast cancer Posted: 15 Dec 2021 10:27 AM PST Depleting copper levels may reduce the production of energy that cancer cells need to travel and establish themselves in other parts of the body by a process referred to as metastasis, according to a new study. The discovery of the underlying mechanisms of how copper depletion may help reduce metastasis in breast cancer will help inform the design of future clinical trials. |
| Better identification of sesame in food packaging needed to avoid anaphylaxis Posted: 15 Dec 2021 10:27 AM PST A new study found that among those who self-reported an allergic reaction to sesame, more than 56% of products which contained sesame did not declare sesame on the label. |
| 'Drink your peas!' Benefits of supplementing cow milk with plant protein Posted: 15 Dec 2021 10:26 AM PST Scientists have developed a novel method of supplementing cow milk with vegetable protein using readily available current dairy processing equipment. A new report presents the study, which may open opportunities to create new functional, multisourced dairy products that could help bolster declining fluid milk sales in the United States. |
| Brain study on how to slow down climate change Posted: 15 Dec 2021 08:32 AM PST When it comes to climate-friendly behavior, there is often a gap between what we want and what we actually do. Although most people want to see climate change slowed down, many do not behave in an appropriately sustainable way. Researchers have now used brain stimulation to demonstrate that the ability to sympathize with the future victims of climate change encourages sustainable behavior. |
| Gallic acid and stretching decrease osteoarthritis markers in cartilage cells Posted: 15 Dec 2021 08:32 AM PST Researchers used gallic acid, an antioxidant found in gallnuts, green tea and other plants, and applied a stretching mechanism to human cartilage cells taken from arthritic knees that mimics the stretching that occurs when walking. The combination not only decreased arthritis inflammation markers in the cells but improved the production of desired proteins normally found in healthy cartilage. While still at an early stage, the findings suggest a new procedure could be developed to treat cartilage cells extracted from a patient to grow a supply of cells or a tissue to be re-implanted. |
| Immune system responds to mRNA treatment for cancer, researchers find Posted: 15 Dec 2021 08:32 AM PST Adding messenger RNA, or mRNA therapy improves the response to cancer immunotherapy in patients who weren't responding to the treatment, new research shows. Immunotherapy uses the body's immune system to prevent, control and eliminate cancer. |
| Scientists find new details about how immune system builds long-term memory Posted: 15 Dec 2021 08:32 AM PST Experts in Japan have identified a fundamental part of the immune system's long-term memory, providing a useful new detail in the pursuit to design better vaccines for diseases, ranging from COVID-19 to malaria. |
| Good mental health in young adults born after assisted reproduction Posted: 15 Dec 2021 08:32 AM PST Use of assisted reproductive techniques (ART) does not lead to poorer mental health in children across adolescence and young adulthood, according to a large observational study. The study found a slightly higher risk of obsessive-compulsive disorder for those born after ART but this was explained by parental background factors. |
| Despite cleaner air, pollution disparities for people of color remain across the US Posted: 15 Dec 2021 05:20 AM PST Researchers investigated disparities in exposure to six major air pollutants in 1990, 2000 and 2010 by comparing models of air pollution levels to census data. While overall pollutant concentrations have decreased since 1990, people of color are still more likely to be exposed to all six pollutants than white people, regardless of income level, across the continental United States. |
| Researchers first to predict when bacteria may become resistant to antibiotics Posted: 15 Dec 2021 05:20 AM PST Scientists have spotted signs of 'pre-resistance' in bacteria for the first time -- signs that particular bacteria are likely to become resistant to antibiotics in the future -- in a new study. |
| SARS-CoV-2 protein interacts with Parkinson’s protein, promotes amyloid formation, study finds Posted: 14 Dec 2021 10:51 AM PST Researchers have shown that, at least in the test tube, the SARS-CoV-2 N-protein interacts with a neuronal protein called alpha-synuclein and speeds the formation of amyloid fibrils, pathological protein bundles that have been implicated in Parkinson's disease. |
| Posted: 14 Dec 2021 07:42 AM PST A new approach by chemists could help to significantly improve diagnostic tests based on PCR. The enzymes used are triggered by light pulses. |
| An enemy within: Pathogens hide in tissue Posted: 13 Dec 2021 03:15 PM PST Antibiotics cure many bacterial infections. However, some patients suffer a relapse. A research group has now discovered why some bacteria can survive antibiotic therapy. The team uncovered where the bacteria hide in the body and how the body's own immune system also plays an important role. |
| Posted: 13 Dec 2021 01:01 PM PST Humans and fruit flies respond to many of the same tastes -- sweet, salty, bitter and so on. The receptors that identify these substances, however, are very different between us and insects. Except when it comes to sour. |
